Y 2 isthe shock receptaele; Which comprises the frame 3, on which aiie hinged the gates 4,

wh ch serve tofform the bottom of the receptacle'when the latter is in the..positiolr shown. in Fig.1.. The-sheaf receptacle is provided with trunnions or pivots 5, b means of which it is pivotally connected with the ends of the links or rock arms 6 ofunequal length. It will be noted that one pair of these pivots is adjacent to the forward end of the receptacle and the other adjacent to the rearward end of the receptacle (see Figs. 1 and 3). The lower ends of the rock armsfi are pivoted at 7 on the main frame of the ap aratus. At the forward end of the frame a discharge shaft 8 is journaled in suitable bearings 9. This shaft is provided with the cranks 10. Each crank is pivotally connected with a pitman 11, and each pitman is pivotally connected with one of the forward rock arms 6. The ates are normally held closed, as shown in i 1, by means of locks 12, which are journa ed on suitable pivots 13, forming part of the hinges 14 of the gates 4. Coil springs 15, connected at one end to the pivots 13 and at the other end to the locks, tend to maintain the locks in the position shown in Figs. 1, 3 and 4, in which their bent ends engage the under or rearward sides of the pivots 5. The hinges are thus prevented from turning on the tubular frame 3, and the gates securely held in the position shown in Figs. 1 and 3.

In order that the locks may operate to gether those at each side of the receptacle are pivotally connected to a rod or link 16. This rod, it willloe seen, is normally on the opposite side of the ivots 5 to the locks, w nch latter are bent downwardly to enable them properlyuto engage the pivots 5. When the receptacle. is tilted to its vertical position, as hereinrlfter described, the lower locks engage the trips i? seen to the frame of the shocker at each side tl These trips are so located that they engage the lower looks just before the shock receptacle reached its lowest position. (onscquently as the shock receptacle moves downward the locks are lifted up and as the gates swing open pass over the tops of the pivots 5. The gates, when the locks are raised, are swung open b y -means of springs 18, each coiled on and connected at one end to the rece tacle frame 3 and engaging the gate with its other end. These springs are, however, not essential as the dumped shock itself will cause the gates to swing open.

The shock receptacle is preferably rovided with a curved top 19, which extenr s in an arch over the gates. This top is rovided with hinges 20 journaled on one Slt e of the receptacle frame 3. The top extends over towards the other side of the receptacle but is not connected thereto, a suflic-ient opening being left through which sheaves may be deposited in the receptacle. This arched to is normally held stationary by any suita le means. I show for this purpose a clutch 21 longitudinally slidablebut non-rotatable on the frame 3 of the receptacle by means of an ardinary'feather key and key-way. (See Fig; 9

stereo This clutch is provided with a hole adapted to engage the pin 22, or other projectlon from one of the hinges 20 of the arched top. A coil s ring 23 engaging the clutch and any suitab e collar on the frame 3 serves to maintain the 'clutch and the pin in engagement, as shown particularly in Figs. 3 an 9.

Before describing the mechanism shown in Figs. 5, 6 and 7. it will be well to describe the operation of the parts already described.

The movements of the shock receptacle will be best understood on reference to Fig. 8 taken in connection with Figs, 1 and 2. It will be .seen that, owing to the forward and rearward links being of different lengths, and owing to the position of the pivots of these links and the position of the front and rear pivfits 5 between the receptacle and the ends of the links, as the crank shaft 8 is rotated to the position shown in dotted lines the front pivots 5 travel from the front to the rear of the are 24 while the rear pivots 5 travel from the front to the rear of the arc '25, and then move forward again to a point intermediate the ends of the are, as shown. The result of these movements of the front and rear pivots 5 is that the shock receptacleis first moved rearwardly and upwardly while maintaining very nearly the normal approximately horizontal position shown; but as the movements of the parts continue the receptacle is tilted quickly and dropped slightly to the position shown in dotted lines in Fig. 8. Though I show rock arms of different lengths for the purpose of effecting these movements it is evident that any other means which would cause the pivots 5 to travel in the arcs 24 and 25 in the manner shown would answer the purpose of my invention. The results of the movements described are important. A certain amount of backward movement is given to the receptacle which partly compensates for the forward motion of the apparatus when the latter is connected with a harvester-binder. The upward movement allows the corner of the receptacle nearest to the ground to swing without touching the latter, as would be the case if the receptacle were rotating on stationary pivots. The downward drop as the receptacle reaches a substantially vertical position serves to cause the receptacle to partly follow the shock as the latter-drops so that the shock is supported until the last possible moment of time. As the tilt to the vertical takes place on the rearward or upper pivots 5 there is scarcely any forward movement to the top of the shock, which thus drops to the ground. under the most favorable conditions to insure its standing erect when the receptacle has passed away from it. As soon as the shock receptacle reaches the vertical position the locks 12 are released, as already described, and the gates open up as the recep- 85 from the position shown in full lines in Fig. 8 v ,v

r already described,

tacle -is drawn away from the shock leaving the latter standng on the field.

The shock receptacle being operated, as y the rotation of the shaft 8, it becomes necessary, inorder that the shock rece tacle remain stationary a. sufficient length of time to enable it to be drawn away from the shock by the forward movement of the machine, to provide means for, driving the shaft which will automatically produce this dwell. For this purpose I provide the mechanism. shown more particularly in Figs. 5, 6 and 7.

()n the bracket 26 supporting the bearing of the inner end of the shaft 8 is journaled a driving shaft 27 in axial alinement with, the shaft 8. To the shaft 27 is secured the hub of the clutch member 28, the inner side of the periphery of which is provided with a plurality of teeth 29. To the shaft 8 is'secured the arm 30 carrying the ivotedfclutch dog 31, the outer end of which is adapted to engage the teeth 29. A coil s ring 32 connects the tail o the dog with the ub of the arm 30 and tends normally to throw the other end of the dog to engage the teeth 29. A catch 33 extends laterall from the end of the dog 31, and then radial y. A trip 34 is formed on a bar 35 having bolt and slot connections 36 with the bracket 26 so as to be slidable thereon longitudinal of the shafts 8 and 27. The

coil spring 37, secured to the bar and to the bracket 26, normally maintains the trip in the osition shown, in which it engages the catch 33 and disengages the dog from the clutch. At the opposite side of the clutch to the trip 34 is a second bar 38 provided with a bolt and slot connection 39 with the bracket 26' whereby it is adapted to slide on the bracket radial to the shafts 8 and 27. A trip 40 is formed on this bar in the path of the catch 33. A lip 41 is also formed at the other side of this bar in the path of the V-sha ed lugs 42, formed on or secured to the bac of the clutch member 28. A spring 43, engaging the bar 38 and the bracket 26, normally maintains the bar 38 in the position shown.

-When it is desired to dump the shock from the shock receptacle the bar 35 is moved to disengage the trip 34 from the catch 33. The spring 32 immediately causes the dog 31 to move outwardly in osition to be engaged by one of the teeth of the clutch member 28,

which latter in practice-will be continuously-- driven from a harvester-binder through the mediumof the shaft 27 As soon as the dog is engaged with the clutch member the driving shaft and the dischargeshaft rotate together and the shock receptacle, through the medium of the crank and itman connections already described, is tilte tothe vertical position. One half revolution of the shaft is all that is required to effect this movement. The catch 33 at tliis'time engages thev trip 40,

are the dog 31- isthrown out of eng with the clutch member 28, causing the dwell-in the movements of the shock receptacle already referred. to. This dwell lasts until one of the lugs 42 moves around into engagement with the lip 41, thus pressing back the bar 38 and causin the trip 40 to release the catch 33. This a lows the. dog to again engage the clutch member, and the discharge shaft is once again driven until the parts reassume their original position. At this moment the catch 33 \again engages the trip 34, and the dog is once more thrown out of enga ementwith the clutch member 28.

t is important that the shock'receptacle be as short a time as ossibleawa from its normally approximate. y horizonta )osition, and as sometime is consumed by t e dwell during which the shock is assing away from the rece tacle, orrather t e receptacle from the shoe it is important to close the gates forming the bottom as rapidly as ossible after the discharge of the shock. I t erefore provide means;by which the closing-movement of the gates is commenced substantiallysimultaneously, with the commencement of thereturn movemen't of the shock rece tacle to its normal position. To effect this 0 osing movement I provide the stationary converging bars 44 connected to the frame 1. These bars are so located that the engage the edges gether until, when the rece tacle has -re- .sumed its normal position, t e gates have been closed sufficiently to allow the locks 12 to slip over the. pivots 5 and rengage themselves therewith, as shown in Figs. 1 and 4.
